Solvents Organic solvents can exert a variety of corrosive effects on composites. Small polar molecules, such as methanol and ethanol, for example, may permeate the corrosion liner, causing some swelling and blistering. Chlorinated solvents, chlorinated aromatics, as well as lower aldehydes and ketones, are especially aggressive and can cause swelling and spalling of the corrosion liner surface. Corrosive environments containing low levels of solvents may still exert significant effects depending on the solvent involved and the properties of any other materials present. Best results in solvent environments are obtained by using resins with high crosslink density, such as DION& 9400, DION® 6694, and DION® 490. Static Electricity Resin/ glass composites are non-conductive materials, and high static electric charges can develop inducting and piping. Static build-up can be reduced by using conductive graphite fillers, graphite veils or continuous carbon filaments in the surface layer. Use of copper should be avoided because it can inhibit the resin cure. FDA Compliance The various versions of DION® 382, DION" 6631, DION® 490, DION® 9102 DION® 6334, and DION® 9100 conform to the formulation provisons specified for food contact in FDA Title 21, CFR 177.2420. These resins may be used for food contact when properly formulated and cured. It is good practice to follow the general curing and surface preparation techniques that apply to potable water, as described herein. It is the responsibility of the manufacturer of composite materials to ensure conformance to all FDA requirements. USDA Applications USDA approvals must be petitioned directly from the USDA by the fabricator. Typically, any product which conforms to the requirements of FDA Title 21, CFR 177.2420 will be approved.
